{"product_id":"809200-1","title":"Ground Cable Heating Cable 25W","description":"\u003cp\u003e4.3 meters length, double-insulated cable for approx. 0.5 m². 25W (without thermostat)\u003c\/p\u003e\n\n\u003cp\u003eHeated soil cable offers the most flexible way to provide bottom heat to your seed trays. The heating capacity can be increased by 1) placing the U-shaped windings closer together, 2) purchasing a cable with a higher wattage, or 3) by spreading a thinner layer of sand over the cable. To prevent heat loss, it is advisable to use polystyrene foam board as a base, then lay out the cable on top, followed by a layer of sand or an aluminum sheet to distribute the heat. The seed trays can then be placed on this. Use a soil thermometer (e.g., 809155 and 809157) to monitor the temperature.\n\u003cbr\u003eTip: For precise temperature control, use a reliable thermostat (see 809244), which must be purchased separately.\u003c\/p\u003e\n\u003c!-- SEARCH-NAMES-START --\u003e\n\u003cp\u003eNames:\u003cbr\u003e\nAlso known as: Heating cable\u003c\/p\u003e\n\u003c!-- SEARCH-NAMES-END --\u003e","brand":"Vreeken","offers":[{"title":"4.3 m","offer_id":44177582522421,"sku":"809200.1","price":39.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/9092\/3573\/files\/809200.jpg?v=1750793723","url":"https:\/\/www.vreeken.nl\/en\/products\/809200-1","provider":"Vreeken's Zaden","version":"1.0","type":"link"}
